Links do not automatically update

I have built a summary spreadsheet that pulls information from multiple spreadsheets to display on our Intranet through Sharepoint. When I open the spreadsheet I am prompted to update the links. I want that to be automatic so that employees do not see that everytime they open that page of the intranet. Under Edit/Links I have set the update to "Automatic" and I have set the Startup prompt to "Don't display the alert and update links" yet I continue to get the alert. Is there another flag I am missing. Thanks.

I am not sure if this would work!

Sub auto_open()
Application.DisplayAlerts = False
End Sub
